CHARLES E. EVANS, 0F WEED, CALIFORNIA.

STILE AND RAIL RABBETER.

To all whom it may concern:

Be it known that I, CHARLES E. EVANS, a citizen of the United States, residing at Weed, county of Siskiyou, State of California, have invented certain new and useful Improvements in Stile and Rail Rabbeters, of which the following is a specification.

This invention relates to rabbeting machines and more particularly to mechanism which may be attached to machines adapted to rabbet door stiles so that the edge of the stile will automatically be undermined by a groove along the portion of the stile which receives the glass.

The objects of the invention are to provide a mechanism for this purpose which may be attached to the usual stile rabbeting or stick ing machine or which may be operated independently thereof and which is adjustable to make the proper cut in stiles of different lengths and also to cut grooves in the stile to correspond with the length of glass which it is desired to use in the door.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a side elevation of a rabbeting machine having my invention applied thereto; Fig. 2 is a plan view of Fig. 1; Fig. 3 is an end elevation of Fig. 1; Fig. 4 shows the traction wheel partly in side elevation and partly in section; Fig. 5 is a transverse section on the line 55 of Fig. 4; Fig. 6 is a detailed view of one of the adjustable segments of the traction wheel; Fig. 7 is a view of a portion of a door showing the top rail removed from the stile; Fig. 8 is a side elevation of a completed door, and Fig. 9 is a transverse section on the line 9-9 of Fig. 7

Referring to the drawings, it will be seen that I have illustrated somewhat diagrammatically a rabbeting or sticking machine adapted to plane the edge of the door stiles. This machine consists of the frame 10 upon which is mounted a bed 11 and a shaft 12, the latter carrying the usual knives or cutters 13 which suitably plane and rabbet the edge of the stile 14. The stile 14 may be fed through the machine in any suitable manner, such as by means of the feed rolls 15. The sticks 14 from which the stiles are formed are passed through the machine in the direction indicated by the arrow, one stick directly following the other, with their ends in contact.

Specification of Letters Patent.

Application filed November 2, 1911.

Patented May 19, 1914. Serial No. 658,224.

Before describing my invention in detail I will now describe its purpose in connection with. the parts forming the door.

The door comprises the stiles 16 and 17, the top rail 18, the bottom rail 19 and the intermediate rails 20 and 21. By this an rangement a space 22 for a glass is provided. In passing the stiles through the rabbeting machine the edge of the stile will be planed to form the curves 23 and 24 and the groove 25, this groove being for the purpose of receiving the glass and also for receiv- 111g tongues which are formed on the rails 18, 19, 20 and 21. In order to permit the glass to be inserted after the parts of the door are put together, it is necessary to cut away the material at one side of the groove 25 and replace the same by a piece of molding which is nailed to the stile after the glass has been inserted. It is the object of the present invention to cut a groove 26 in the side of the stile so that this material may be removed to permit the insertion of the glass by simply making transverse cuts at the points 27 and 28 of the stile. In order to adapt the machine for cutting the groove 26 to stiles of different lengths and also to cut a groove corresponding tothe length of glass to be used, it is necessary to provide means for adjusting the mechanism.

Referring now to the drawings showing the machine, it will be observed that the same comprises a traction wheel 30, which is mounted on a shaft 31 carried by the arm 32, the latter being carried by the shaft 33 which is mounted in bearings 34 and 35, carried by a pedestal 36 on the frame 10. The traction wheel 30 consists of the disk 37 which is secured to the hub 38 of the wheel and the disk 39 which is bolted to one side of the disk 37 by means of the bolts 40. The outer portion of the disk 37 is provided with radial grooves 41 having parallel sides and which receive the arms 42 on the circumferentially arranged segments 43. These segments are provided with suitably formed teeth 44 and are adapted to rest in the groove 25 of the stile as the latter moves through the machine so that the wheel 30 will be rotated by the stile. Each of the arms 42 is provided With a pin 45. These pins engage slots 46 formed in the disk 39. The disk 39 is also provided with slots 47 through which pass the bolts 40, the latter being secured in screw-threaded open ings 48 in the wheel 37 It will be nnder stood that by the construction just described the segments 43 will be moved in a radial direction, either outwardly or inwardly by an angular movementof the disk 39 relative of the disk 37, owing to the location of the slots 46 which are engaged by the pins 45 and the arms 42 which are carried by the segments. F or the purpose of moving the disk 39 angular-1y with respect to the disk 37 a pivot 49 is secured to the former and passes through one of the openings 50 in the disk 37. A screw-threaded nut 51 is pivotally connected to one of the arms of the disk 37 and is engaged by the screw 52, which has one end thereof secured to the pivot 49, the opposite end being provided with a suitable hand wheel 53 for the purpose of rotating the screw. hen it is desired to move the disk 39 relatively to the disk 37, the nuts 40 will be loosened and the hand wheel 53 rotated until the disks are in their desired position, when the nuts 40 will be tightened and thereby clamp the disks together.

In the operation of the machine the wheel 30 will make exactly one complete revolution in moving the length of each stile and in order to provide for different lengths of stiles it is necessary to make the circumference of the wheel adjustable. For the purpose of indicating the length of the circumference of the wheel for any given adjustment, a pointer 54 may be attached to the disk 37 and a suitably marked scale 55 may be formed on the inner side of the disk 39 so that the length of the circumference of the wheel will be indicated by the position of the pointer on the scale.

For the purpose of cutting the groove 26 in the side of the stile a circular saw 56 is secured to the upper end of the vertical arbor 57 which is mounted in bearings 58 and 59, carried respectively by arms 60 and 61, secured to the vertical shaft 62. The shaft 62 is mounted in bearings 63 and 64, secured to the frame 10 and has at its lower end an adjustable pivot or step bearing 65 by means of which the shafts 57 and 62 may be adjusted vertically.

For the purpose of driving the saw 56 a suitable pulley 66 may be secured to the shaft 57 and driven from a pulley 67 on the shaft 62 by means of the belt 68. The pulley 67 may be loose on the shaft 62 and driven by the belt 69 from any suitable source of power. The upper end of the shaft 62 carries an arm 70 having the bifurcated end 71 which receives the cam roller 72, the latter engaging the side of the wheel 30. The wheel 30 has mounted circumferentially thereon the cams 73 and 74, both of which are arranged to engage the cam roller 72 as the wheel rotates and the latter of which is preferably secured to the wheel so that it may be adjusted relatively to the former. For the purpose of adjusting the cam 74, slotted arms 75 are carried thereby and these arms are engaged by the bolts 76 which are suitably secured to the disk 37 As the stile 14 moves through the machine the wheel 30 will be rotated and at the proper instant the cam roller 72 will engage the cam 73 and be moved outwardly thereby, swinging the saw 56 into position to cut the groove 26 in the stile. -When the roller reaches the end of the cam 73 it will continue to roll on the cam 74 until the end 77 of the latter is reached. lVhen the roller reaches the end 77 of the "cam 74, it will move inwardly against the wheel 30 because of the action of the spring 78, one end of which is connected with a lug 79 on the arm 61, the other end of the spring being suitably fixed to the frame 10 or any other object. For the purpose of indicating the length of the groove 26 which will be cut a scale 80 may be arranged on the disk 37 so that the end 77 of the cam 74 in any adjusted position will indicate this length.

From the above description it will be understood that as the stiles move through the machine in succession, the cams 73 and 74 will cause the saw 56 to cut the groove in the side of the stile at the proper position and the wheel 30 will make one complete revolution for each stile so that the grooves will be cut uniformly and accurately in all of the stiles. When it is not desired to use the mechanism, the wheel 30 may be lifted out of engagement with the stile by means of the lever 81 which is fulcrumed on a suitable bracket. 82 and is connected with the arm 32, carrying the Wheel 30 by means of the rod 83, so that by drawing one end of the lever 81 downwardly the wheel 30 will be lifted out of contact with the stile. A suitable rod 84, having its lower end arranged to be secured to any fixed part of the machine, may be provided for the purpose of holding the wheel 30 in inoperative position.

WVhen it is desired to use the invention in dependently of the sticking machine, it is only necessary to provide suitable feed rollers to move the stiles through the machine.

It is obvious that various changes in the details of construction may be made in the apparatus as shown and described, without departing from the spirit of my invention and it will, therefore, be understood that the invention is not limited to the precise de tails of construction shown and described.
